Changing batchsize (reducing it) will increase the amount of memory and won't free after increasing it back

Changing batchsize (reducing it) will increase the amount of memory the app takes. Increasing it back doesn't shrink the memory used.

After further research, this issue seem old (it appear even at tag 12.10 !)

It may be time to use valgrind or any other other memory monitoring tools

We noticed a memory leak on a specific computer, while fixing this issue, causing a leak while being in the GUI (without doing anything), it was caused by a too old version of Nvidia Version (535.161.07(Linux)/538.33(Windows)) which had a known issue which get fixed afterwards
